Plots For Assessing Model Fit. Both QQ and PP plots can be used to asses how well a theoretical family of models fits your data, or your residuals. To use a PP plot you have to estimate the parameters first. For a location-scale family, like the normal distribution family, you can use a QQ plot with a standard member of the family.

Layouts. As of v0.7.0, Plots has taken control of subplot positioning, allowing complex, nested grids of subplots and components. Care has been taken to keep the framework flexible and generic, so that backends need only support the ability to precisely define the absolute position of a subplot, and they get the full power of nesting, plot area alignment, and more.

Technically speaking, a Q-Q plot compares the distribution of two sets of data. In most cases, a probability plot will be most useful. A probability plot compares the distribution of a data set with a theoretical distribution. The R function qqnorm( ) compares a data set with the theoretical normal distibution.

The x limits (min,max) of the plot, or the character “s” to produce symmetric forest plots. This is particularly revelant when your results deviate substantially from zero, or if you also want to have outliers depicted. (e.g. xlim=c(0,1.5) for effects from 0 to 1.5).
